hiding Iframe vertical scrollbar

Hi
I have a test site where I'm trying to display anther page inside it using an Iframe.

here is the url:
http://draigweb.co.uk/test/index.html

Basically it is showing a 'grayed out' vertical scrollbar, I want to completely hide all scrollbars so it looks like part of the page.

Here's the html on the iframe, it has inline CSS:

See our events Calendar.

Does anyone have any ideas how to turn off the vertical scrollbar?

Many thanks in advance!
